Definitions

  • This invention relates to a process for superimposing at least two flexible layers, particularly a rear and front panel of an article such as a slip in the textile and knitted goods industry.
  • the invention also relates to an apparatus for superimposing at least two flexible layers for carrying out this process.
  • the conventional manufacture of slips requires three preliminary work stations for the preparation of the slips.
  • the first station comprises bringing the edge seams of the two layers of fabric, front to back.
  • the second station comprises sewing the gusset along its median axis on the front panel.
  • the third station comprises finally spreading out the gusset on the front panel, from one side to the other of the median seam, and fixing it at two points in order to keep it in this position for the following operations.
  • the present invention has as its primary object to substitute for the assembly of these preparatory stations a production in a single pass at a unique work station.
  • the invention provides a process for superimposing at least two flexible sheets, in particular the front and rear panel of an article such as a slip, in the textile and knitted goods industry, and is characterized in that it comprises forming a stack of each type of layer or sheet, and placing these stacks on a plate, then for each of these stacks:
  • the layers are arranged astride a deposit member which comprises a vertical plate having with an upper horizontal deposit edge.
  • the layers are preferably arranged, initially on two deposit bars arranged on opposite sides of the deposit plate, parallel to the upper edge of the latter and movable between a position slightly elevated with respect to the upper edge and a lower retracted position.
  • each layer is carried out, preliminarily, onto the two deposit bars in such a manner that that layer does not displace the lower, previously deposited layers, when it is brought above the deposit plate. These deposit bars are then retracted to allow the particular layer to fall astride the deposit plate.
  • the transported layers are restrained by aspiration means in the vicinity and ahead of the deposit member in such a manner as to suppress any risk of waves in these layers.
  • gusset panels and front panels are arranged on the plate with a centrifugal displacement with respect to a stack of back panels so that the gripping assembly seizes each front and each gusset along a line near a longitudinal extremity of the latter and each back along an intermediate line between its extremities.
  • each front panel and each gusset panel is laid astride the deposit plate, without a longitudinal fold.
  • each back is folded longitudinally when placed on the deposit plate.
  • the deposit member may advantageously be subjected to a translational movement toward or away from the plate in order to adjust the position of the deposit member and to obtain a superimposition of the layers with one of their longitudinal edges aligned.
  • the three layers are thus deposited in a superimposed manner in an appropriate position to permit the operator to carry out on the same sewing machine, first the axial sewing of the gusset, then the two sewing steps of the side. During these operations, the longitudinal folding of the back avoids the situation in which the back would be sewn when the axial sewing of the gusset is carried out.
  • the invention also relates to an apparatus for superimposing at least two flexible layers, in particular a front panel and a rear panel of an article such as a slip, in the textile and knitted goods industry, characterized in that it comprises:
  • a stack plate provided with means for holding and positioning at least two stacks of sheets arranged thereon
  • a gripping assembly associated with actuating means and adapted to grip at least one sheet from a stack, and to release it on command
  • FIG. 1 is a perspective view, with one portion of the covering removed for clarity, showing an apparatus according to the invention
  • FIG. 2 is a longitudinal cross-sectional view along a vertical plane A--A of FIG. 1 and view in the direction of the arrows;
  • FIG. 3 is a transverse cross-sectional view along a vertical plane B--B of FIG. 1 and viewed in the direction of the arrows;
  • FIG. 4 is a longitudinal cross-sectional view along horizontal plane C--C of FIG. 1 and viewed in the direction of the arrows;
  • FIGS. 5a through 5k are schematic views illustrating the an operating cycle of the process and apparatus.
  • FIGS. 1 through 4 The machine shown in FIGS. 1 through 4 is intended to superimpose three flexible sheets such as a front panel, a rear panel and a gusset of a slip.
  • This machine comprises, firstly, a horizontal circular stack plate 1 resting through its lower face on three wheels 2 caused to rotate by means of a driving motor 3, and arranged on a support chassis 4.
  • This plate 1 includes holding and positioning members for the respective front, back and gusset stacks. These positioning members are arranged on the plate 1 is such a manner as to define between them angles of 120°, and are formed by ribs 5 near the center of the plate and guided vertically to assure by their weight the pinching of a longitudinal edge of the layers, for example the edge of each of these layers.
  • At least one of these holding ribs 5 is provided with means for controlling its position and arranged to radially adjust this position on the stack plate 1.
  • This controlling means comprises a scale arranged radially on the plate 1 and carrying carrying toward one of its extremities a rib 5, the scale comprising a longitudinal slot permitting adjustment of its position by means of a pressure screw 7 housed in the slot and adjusted through an opening provided in the plate 1.
  • the holding bars or ribs 5 for holding and positioning the stacks of gusset panels and front panels are arranged with a centrifugal displacement with respect to the ribs for holding the back panel stack.
  • the means 2, 3 for causing rotation of the plate 1 is adapted to cause it to turn one-third of a revolution at a time in such a manner as to successively bring each stack directly below a gripping assembly adapted to grasp one sheet from the stack.
  • the plate 1 is also subjected, after each third of a revolution, to a raising motion which lifts the stacks toward the gripping assembly and permits the latter to grip the upper sheet thereof.
  • the machine comprises a pneumatic cylinder or jack 8 arranged vertically and provided with a rod carrying near its end a horizontal support plate 9. From a retracted position where the horizontal support plate is situated a distance below the plate 1, the cylinder 8 is adapted to be deployed so that the support plate 9 comes into contact with the lower face of the plate 1, raising the plate 1.
  • the upper face of the support plate 9 and the lower face of the plate 1 are provided with conjugate joining structures, adapted to assure the precise rotation and positioning of the plate.
  • These joining structures comprise three female conical indentations 10 formed in the lower face of the plate 1, into which are introduced upon each displacement of the cylinder 8, conical projections 11 provided on the upper face of the support plate 9, which assures at the end of each rotation a precise position of the plate 1.
  • the gripping assembly itself comprises a frame 12, carried by a movable member 13a of a rodless pneumatic cylinder 13 arranged horizontally, and on which are mounted four aligned gripping heads 14, such as described in U.S. Pat. Nos. 4,635,918 and 4,822,020, and application for certificate of addition 88.06752.
  • This gripping assembly is caused to undergo a horizontal translational movement bringing it above a vertical plate 15 provided with an upper horizontal deposit edge arranged essentially in the same horizontal plane as the plate 1, in the raised gripping position of the plate 1.
  • This deposit plate 15 is supported by vertical feet 16 slidingly mounted along two horizontal guide bars 17 so as to permit a translational moving of this plate 15 toward and away from the plate 1.
  • This translational movement is brought about by a pneumatic cylinder 18 arranged horizontally and the rod of which is fixed to the vertical feet 16 carrying the plate 15.
  • two deposit bars 19 which are subjected to a vertical reciprocating movement between a slightly elevated position with respect to the edge of the plate 15 and a lower retracted position.
  • the deposit of each sheet is carried out on the deposit bars 19 in such a manner that the upper sheet of the superimposition does not displace the one or more sheets below, when it is brought above the deposit plate 15.
  • the deposit bars 19 are then retracted after each deposit in order to allow the layer concerned to fall onto the deposit plate 15.
  • the deposit bars 19 are carried by two holders 20 fixed to a movable member 21a of a rodless cylinder 21, vertically disposed. These two holders 20 are disposed on opposite sides of a vertical guide plate 22 provided with an upper portion on the longitudinal edges of which they are guided by a wheel 23.
  • This guide plate 22, having an upper portion of greater width than its lower portion, permits during the ascending movement of the cylinder 21, to be subjected to a movement drawing nearer to the bars 19 such that these bars are positioned essentially side-by-side above the upper edge of the plate 15.
  • the bars 19 separate from one another so as to deposit the layer across the upper layer of the plate 15 and to retract from this plate.
  • aspirating means comprising two nozzles 24 arranged on opposite sides of the plate 15. These nozzles 24 function to restrain the fabric of the layers passing thereby so as to suppress any risk of the appearance of undulations and to eliminate angular displacement or other positioning faults in the sheets with respect to the deposit plate 15.
  • blowing nozzles 25 arranged above the plate 15 avoid undulations or folds appearing at the level of the points of the gussets or front panels when they are placed astride the plate.
  • the gripping assembly 12, 14 is positioned above the stack plate 1, directly over the stack of back panels (FIG. 5a).
  • the deposit plate 15 is itself in the advanced position with regard to the plate 1, corresponding to an extended state of the cylinder 18.
  • the cylinder 8 is then extended in such a manner that the upper layer of the stack of back panels contacts the grippers 14 and assures that this layer is picked up in the manner described in French patent No. 84.04804, French certificate of addition No. 86.02951 or the application for French certificate of addition No. 88.06752 (FIG. 5b).
  • the sheet is gripped along an intermediate line.
  • the gripping assembly 12, 14 is then caused to undergo a translational movement bringing it above the deposit plate 15, while the deposit bars 19 are brought to their slightly elevated position with respect to the upper edge of this plate (FIG. 5c).
  • the grippers 14 are then actuated as described in French patent No. 84.04804, French certificate of addition No. 86.02951 or the application for French certificate of addition No. 88.06752, and the back panel is deposited astride the deposit bars 19, while being folded longitudinally on itself (FIG. 5d). The panel is then deposited on the deposit plate 15, followed by retraction of the deposit bars 19, while the gripping assembly 12, 14 is returned toward the plate 1 (FIG. 5e).
  • the rotating plate 1 is then caused to rotate onethird of a revolution, the cylinder 8 being retracted, in order to bring the front stack directly below the gripping assembly 12, 14, whereupon the cylinder 8 is extended in such a manner as to bring the upper layer of this stack into contact with the grippers 14. Contrary to the back panels, and by reason of the centrifugal displacement of this stack of front panels, the layer is then gripped along a line near its end.
  • the deposit plate 15 is brought into its remote position with respect to the plate 1, corresponding to a retracted state of the cylinder 18 (FIGS. 5f and 5g).
  • the gripping assembly 12, 14 is then brought once again above the deposit plate 15, while the deposit bars 19 are subjected to an ascending movement (FIG. 5h), and the front panel is deposited, extended astride the deposit bars 19, without longitudinal folding (FIG. 5i).
  • the front panel After retraction of the deposit bars 19, the front panel is extended on the deposit plate 15 without longitudinal folding (FIG. 5j). Further, this plate 15 is positioned more remote from the plate 1 than during the deposit of the back panel and the front and back panels are perfectly aligned.
  • the gripper assembly 12, 14 comes to grip a gusset panel and deposit it on the deposit plate 15 (FIG. 5k).
  • the three sheets are then superimposed one on the other in an appropriate position to permit carrying out the sewing operation at once.
  • the operator may thus pick up the three layers and achieve on the same sewing machine first the sewing of the holding seam (axial sewing of the gusset), and then the two side seams.
  • the folding of the back avoids the back being sewn when the gusset seam is sewn.
